BAR HOLDING DEVICE FOR LOCKS Filed Dec. 22, 1931 Patented May 16, 1933UNITED STATES MORRIS FALK, OF FITCHBURG, MASSACHUSETTS BAR HOLDINGnnvioa roe LOOKS Application filed December 22, e31; Serial No. 582,561.

This invention relates to an ordinary type of lock and the principalobjects thereof are to provide a simple and inexpensive means ofassembling; to provide a construction which can be put together veryeasily and which will remain in assembled condition without danger ofthe parts becoming detached and particularly to provide a simplified andimproved means for connecting the connecting bar with the rotary plug ofthe lock.

Other objects and advantages of the invention will appear hereinafter.

Reference is tobe had to the accompany- 5 ing drawing, in which Fig. 1is a side view of a lock constructed in accordance with this invention;

Fig. 2 is an end view of the same as indicated by the arrow 2 of Fig. 1;

Fig. 3 is a diametrical sectional View;

Fig. 4 is a side elevation of the plug, and

Fig. 5 is an elevation of the retaining washer.

This invention is capable of application to locks of different kinds. Itis shown for the purposes of illustration as comprising a casing 10 andplug 11 having pin tumblers,

discs or the like, but the locking means are not shown. A key 15 is usedas usual in this so look.

The plug is provided with a slot 12 in the end arranged diametricallyand is also provided with a circumferential groove 13 near the end. Forthe purpose of holding the connecting bar 14 in place without going tothe comparatively laborious and expensive means usually employed thesaid'bar is provided with spread ends 16 adapted to be inserted in theslot 12.

After these two parts are put in position, as indicated in Fig. 3, awasher 19 is introduced over the end of the plug and up against the endof the casing to close the slot, this washer having a pair of inwardlyextending ears 17 for entering the ends of the slot 12 and holding thewasher from turning on the plug and also holding the ends 16 in theslot.

The washer is held in position by a spring looking ring 18 which isexpanded slightly from its normal position and introducedinto,thecircular groove and engages the washer 19 and holds it against thecasing'lO. This ring therefore constitutes the means for holding theparts together. It is applied very readily and being made of springsteel,

preferably, it will remain in place'in the groove and resist all forcesthat may be applied to it in the use of the lock.

hen the lock is removed from the door 0 and it is desired to take itapart the ring can be pried off in an obvious and simple manner so thatthe parts are assembled and disassembled with almost equal facility.This constitutes a very simple means for holding 5 the connecting barwith respect to the plug, reduces the cost of manufacture and the costof assembling and produces a joint which will last as long as any otherpart of the lock.

Although I have illustrated and described only one form of the inventionI am aware of the fact that modifications can be made therein by anyperson skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore, I do not wish to belimited in this respect, otherwise than as set forth in the claims, butwhat I claim is 1. As an article of manufacture, a lock comprising alocking plug having a slot in its end and an exterior groovecircumferentially around it near the end, a connecting bar having aspread end entering said slot and extending across it, means for holdingsaid spread end in the slot, and a spring ring 10- cated outside theplug in said groove to hold said means in position.

2. As an article of manufacture, a lock comprising a casing and a plugrotatably mounted therein, the plug having a slot entering its end anda. groove around the end, of a connecting bar having a spread endlocated in said slot, a washer engaging the end of the casing and havinga passage therethrough for the bar, the groove in the plug being locatedin a position just beyond said washer, and a spring ring in the grooveto hold the Washer in position.

3. As an article of manufacture, a lock comprising a locking plug havinga slot in its end and a groove circumferentially around it near the end,a connecting bar having a wide end entering said slot and extendingacross it, a washer having a pair of inwardly extending ears to retainsaid spread end of the connecting bar, and a spring ring located in saidgroove to hold the washer in position.

4. As an article of manufacture, a lock comprising a locking plug havinga slot in its end, a connecting bar having an end in said slot, and awasher having a pairof inwardly extending ears for the purpose ofturning the washer with the motion of the plug'and, at the same time,retaining the spread end of the connecting bar. 1

5. As i an article of manufacture, a lock comprisinga locking plughaving a slot in its end and a groove circumferentially around it nearthe end, a connecting bar having a spread end entering said slotandextending across it, a washer having a pair of inward- 1y extending earsfor the purpose of turning the washer with the motion of the plug, and aspring ring located in said groove to hold the washer in position.

In testimony whereof I have hereunto affixed my signature. MORRIS FALK.
